A combustion sample sits in a sealed steel bomb at constant volume, immersed in a stirred water bath inside an insulated jacket.
A bomb calorimeter measures heat at constant volume. Therefore the heat measured equals which thermodynamic quantity?
- A
ΔS (entropy)
- B
ΔG (free energy)
- Ccheck_circle
ΔE (internal energy)
- D
ΔH (enthalpy)
Explanation
At constant volume, w = 0, so q_v = ΔE (internal energy change), not ΔH.
